PIVOTED DOOR SUPPORTING CLAMP Filed Aug. 8, 1947 IN VEN TOR. TONY C.TIMS ATTORNEYS Patented Apr. 22, 1952 UNITED STATES PATENT OFFICE2,594,249 rivorsn was rosr e GLAMP its 2- tim y tti a M AppiicationAugust 8, 1%7, erial go; 75L5 2 Claims. (01, n es This invention relatesto door holders, and the primary object is to provide a device of thischaracter for the use of carpenters and other mechanics for holding adoor in an open or partially open position while work is being performedupon the door, such as mortiging the same for the reception of a lock,or for the repairing of a lock, etc.

The device of this invention may be readily applied to, and removedfrom, the door; is easy to manipulate; is effective operation; is .ofsuch a construction, combination and arrangement as to lend itself tomass production at low cost.

The invention together with its objects and advantages will be bestunderstood by reading the following detailed description with referenceto the accompanying drawing, wherein is illustrated a preferredembodiment of the invention, and in which:

Figure 1 is an elevational view of a door holder embodying the featuresof the present invention, andillustrating an application thereof; a doorbeing shown fragmentarily and in side elevation;

Figure 2 is a top plan of the assembly shown in Figure 1.

Figure 3 is an elevational view of the door holder per se and takensubstantially at right angles to Figure 1; and

Figure 4 is a perspective view of the doorengaging jaw forming part ofthe invention.

Referring now in detail to the drawings it will be seen that theimproved door holder comprises, in general, a base frame 5 a doorengaging jaw 6 pivoted to the base frame 5 to swing into and out ofpositive engagement with the bottom edge of the door 1, an operatingscrew 8 threadedly engaged with the jaw assembly 6 for moving the latterinto and out of engagement with the door I, and a head member 9 adaptedto straddle the door 1 andhaving a universal connection iii with thescrew 8 so as to permit relative rotation of the latter for effectingmovement of the jaw assembly 8 to the desired position of adjustment.

The base frame 5 is formed from a single length of metal or othersuitable material bent into a substantial U and is adapted to restvertically on the fioor H as shown to advantage in Figure l. Theupstanding legs E2 of frame 5 accommodate therebetween the jaw and theselegs have vertically spaced apertures l3 to accommodate a pivot bolt Itthrough the medium of which the jaw assembly 5 is pivoted to the frameat a desired height with respect to the floor II or closed bottom end offrame 5.

iii)

Th aw assemb 5 is a so ter ed m metal or th r s itable mesa an s he formo a shell to accommodate the lower free corner of the door I as shown.This jaw assembly 6 includes a substantially horizontal jaw member t5, asubstantially vertical part it, and opposed sides l --l "l integral withthe jaw l5 and vertical part It, as shown to advantage in Figure 4.. Theside members I! are suitably apertured as at' I8 to register withaligned apertures I3 and accommodate the pivot bolt It. Jaw I5 also hasformed integrally therewith an upstanding tooth I9 to positively engagethe lower edge of the door 1 as shown in Figure l.

For the jaw assembly 6 there is provided the aforementioned operatingscrew 8. This screw has a threaded shank portion that threads through athreaded boss 20 provided on the vertical part It on the jaw assembly.The free end of the threaded portion of screw 8 is of ball shape and hasa working fit in a slotted socket formed on a head member 9 to providethe aforementioned universal joint connection IB between the operatingscrew 8 and said head 9, as clearly shown in Figures 1 and 2.

The head member 5 is formed from a single length of metal or othersuitable material and is bent into a substantial U so as to straddle thedoor 7 at the free vertical edge thereof as shown in Figures 1 and 2.The socket forming part of the universal connection l 0 may be formedeither integrally with the head 5 in a single operation, or formedseparately therefrom and secured to the head member at the closed end ofthe U in any suitable manner, as by being welded thereto.

,In using the door holder the door 1' is swung on its hinges to theposition in which it is desired to hold it. The frame 5 is then placedon the floor II in close proximity to the free vertical edge of the doorI with the lower free corner of the door being received within the jawassembly (5, and the head 9 placed in straddling position on the freevertical edge portion of the door I. The operator then turns theoperating screw 8 in a manner to cause the jaw assembly 6 to rock on itspivot 14 in a clockwise direction until the tooth edge It of jaw I5 isforced tightly against the lower edge of the door.

When it is desired to release the door, the operating screw 8 is turnedin a reverse direction so as to cause the jaw assembly 6 to swing in acounterclockwise direction on its pivot It so that the tooth l9 swingsdownwardly away from the lower edge of the door 1. The door holder maynow be readily removed.

A door holder embodying the features of this invention will be positiveand eflicient in operation, and the use thereof will not result inmarring, scratching or otherwise injuring either the door or the floor..

Although I have herein shown and describe a preferred embodiment of thisinvention, it is to be understood that various changes may be madetherein within the scope of the claims hereto appended;

What is claimed as new is:

1. A door holder comprising a base member adapted to rest on the floor,a shell-like jaw as sembly pivotally mounted on said base member toreceive the lower free corner of a door and embodyinga; substantiallyhorizontal jaw member, a substantially vertical part, and opposed sidesintegral with said jaw member and vertical part, an operating screwthreadedly engaged with the aforementioned vertical part of said jawassembly and extending inthe general direction of the said 'horizontalwjaw member to impinge again'stthe .free vertical edge of the door forrocking Tithe horizontal jaw member into positive engagement with thelower horizontal edge of the door, and a pivot bolt intermediate thefree edge of the said J horizontal jawmember and said operating screwpivotally connecting said jaw assembly with said base member. 2. A doorholder comprising a substantially U-shape base frame, a jaw assemblycomprising a shell-like member including a substantially horizontal jawmember, a substantially vertical part,

4 i and opposed sides integral with said substantially horizontal jawmember and vertical part, a pivot bolt extending transversely throughsaid jaw as- 'sembly and engaged in apertures in opposed portions ofsaid base frame and opposed sides of the jaw assembly 'pivotallyconnecting the latter with the base frame, an operating screw threadedlyengaged with the aforementioned vertical part of the jaw assembly, adoor engaging head swivelly mounted on one end of the screw, saidsubstantially horizontal jaw member having a free edge portion providedwith an upstanding door engaging tooth; said pivot bolt being disposedintermediate the door engaging tooth and operating screw, and saidoperating screw extending in the general direction of said horizontaljaw member.
